use and the commercial production of available In the handling of coin,assmall change, in many businesses it has become increasingly'importantthat balances be accurately checked with- I out loss of time and thatthe assorted specie be capable of final audit on transfer to eachsucceeding custodian who, in taking 'over the work of his predecessor inoflice, can readily check the accuracy of the predecessors count whichhe usually is required to" acknowledge by some form 10 of receipt. 7

As coins of various denominations vary considerably by reason of wear,those of any denomi-' nation, while beinglpassable, maybe increasinglythinned in the course of their use. This wear v produces degrees ofvariants in group measure ment which makes the mechanics oftheirhandlinga difficult problem. I t

Ordinary sorting or storage are usually cared for by the laws of averagein thickness, so that generally open stack methods are acceptable as abasis of computation of totals of' fractional specie. t

However, where varied specie must be sorte and counted under hurryingconditions, theneed of inexpensive coin racks or like exact handlingconvenience has become one approximating practical necessity. Forexample, the necessary changes in custodian responsibility in businessattentive inspection. This makes possible accurate financial totals,fair to the users as mutually capable of quick check and shiftofresponsibility. As illustrative of my invention I have shown in theaccompanying drawings a rack basis of assortment and computation bywhich one custodian may prepare for rapidly transferring to another :50an accumulation of. specie of value which may be widely Variant attimes. t l

As indicated in the drawings, racks according to my invention mayadvantageously be made of 2 0 laminae of woodorlike inexpensivematerial, such asthestripsl. l 1

The strips 'are. formed of a laminal thickness equalto that of apredetermined number of coins of like denomination. For this basis ofmeasure- 2 5 ment Ipreferably stack and caliper. new or unworn coins tominimize the possibility of careless insertion of thin or worn coins asextras which would destroy thefaccuracy of count which is based on thegrouping of a predetermined number q to of such coins in relatively.small groups. 4 The grouping is conveniently provided for by pocketsformed by scallops 2 of semi-circular form and of the diameter of thecoin lto be accommodated. The pockets are preferably half-round and Eneat diameter so as to support coins at and below In practice thelaminae may be formed by boring the strips I from template spacingsiwithbits such as the so-called Forstner bits, centered,

and spaced symmetrically on a common line at t the median plane of thestrip.

. ;As indicated in Figs. .l to 4, the strips which are to yield thelaminae may be of double width so thatwhen sawed with a very thin saw ontheir median plane as C'D, there are formed, two

strips or laminae scalloped on their edges as above described andindicated at 2. l According to my invention the spacing of the"bitcenters according. to a template may be un-,

equally distanced from one end so that when" such strips are reversed inassembly as alternate laminae their semi-circular scallops are slightlystaggered. -This permits each non-coincident scallop or pocket to bepartly blocked by the 55 laminae next adjacent to the extent of theintersecting arcs of their halfround pockets due to the staggering oftheir centers as above described.

Thus, while each pocket is partially blocked at its 5 open side, coinswill be supported and retained in their assemblies and their staggeringprovides a partial opening sufficient for finger clearance as indicateddiagrammatically in Fig. 6, whether it be desired to pick off a lonecoin or clear a pocket as a unit.

The number of coins held by any pocket or group of pockets according tomy invention should be small enough to be comprehended at a glance.

The basis of predetermination of their number may be conveniently suchas to induce mental additions of such fractional currencyas units sothat totals may be read oif with great rapidity and accuracy on thesimple group basis made possible by consistent racking according todenomination. This is physically checked upon by pocket diameters andbyaxial width, limiting number capacities to readilyobservablecomputative group. 3 s

As indicated in Fig. 5, the plain edge separator strips 3 of thereversed laminal pocket pair may be provided with a scale or numberseries as an assistance in checking the pocket count as by the Romannumerals suggestively indicated. -As the double laminal strip, which isindicated as intended for dimes or silver tencent pieces, represents aminimum two laminae unit, such may be taken-as the minimum widthcharacteristic unit pair where a pair is needed. Coins of largerdenomination or greater thickness'are simply provided for by strips I ofthe thickness of the predetermined number fixed upon for the basis ofcalculation for that denomination as a part of the more comprehensivecollectionhandled by the rank as a whole.

--For example, on the present fractional currency basis the dollar pair,where a pair is used,

is provided on a five coin pocket basis which makes the pair capacityfor each longitudinal unit (IIII II-IVV) equal ten dollars ($10.00).Thus'the total for the pair unit when full would be fifty dollars($50.00). By counting the number of full pockets, or, conversely,subtracting thetotal of empties, the total dollar value of the cache orcollection may be seen at a glance.

On the basis of'the half dollar pair of laminae, each pocket preferablyholds four, or eight half dollars to the lineal progression along thestrips. Such an arrangement would show a total, when the pockets are allfull, of twenty-four dollars ($24.00).

As indicated in Fig. 5, the penny collection may be conveniently caredfor by a five penny pocket basis which gives for each lineal unit whenfull, a value of twenty cents (20) or a total for the pair series whenfilled, of one dollar and sixty cents ($1.60). In some instances I leaveoff one laminae from the top half of Fig. 7 so that the columns ofnickels total'one dollar each and the columns of pennies totaltwenty-five cents (25) each.

As seen in the plan view of Fig. 5, the unequal spacing of the boring ofthe holes relative to the strip ends gives to the severed laminae anefiective difference in length. This affords the simple and easy basisof staggering, preferably at less than a pocket scallop width, so thatthe pocket sides are partly, but not wholly blocked, as diagrammaticallyindicated in Fig. 6. Such an ar- '75rangement provides for the lateralsupport of coins in the pocket without making it a complete block orshut-ofi to digital penetration.

When the double strips l are bored or drilled as before described, andare severed on their median lines C-D, the laminae so secured areassembled, preferably in pairs alternately reversed and arranged ontheir smooth edges with their scalloped edges up. So assembled they maybe glued, bradded or pinned together or otherwise joinedto formalaminated block. This block is preferably framed as by a band 4 forneatness and strength and the protection of the ends of its staggeredlaminae against displacement.

In assembling the laminae of racks according to my invention Ipreferably form the strips l with pin holes 5. These are spacedsymmetrically about the strip center as indicated in Figs. 1-4.

-By threading these holes 5 on assembly pins to hold them temporarilyapart the glue may be brushed on between them. These assembly pins maybe left in. By using enough assembly pins or tight dowels, the glue maybe omitted.

As before explained, these laminae may be of wood. By using dry hardwood great strength is attained by the natural crossings of the grain.Also, by selection of woods of different colors, such as birch andcherry, the laminae are further set off or marked which assists incarrying the eye past empty or partly filled pockets so that alinementis assisted and the observation and count facilitated and confirmed.

' By arranging the unit pairs of pocket sections in related order, therack may be madeto assume columns disposed forready addition or forcarrying totals with the coin groups making a basis of addition of subor minor units of denomination or more comprehensive totals.

In another form of rack according to my invention, I dispose the coinpockets of the same denomination transversely of the laminae as in Figs.7 and 8 instead of ranging them longitudinally as in Figs. 1 to 6.

Referring to the plan view of Fig. 6 it will be seen that the transversegrooves 26 are preferably formed as a series of pockets 2!. As shownthey are cylindrical so that they may be considered as having their axesrelatively staggered;

The individual pockets 2! are really only semicircular grooves formed inmain general trough cavity 20. This means that the general or maintrough cavity is slightly interrupted by the staggerof the edges ofthese pockets 2| which intersect as overlapping or intersecting arcuateedges or shoulders when considered in their relation to each other asviewed laterally in Fig. 8. The pockets 2| will therefore be seen togenerally correspond to my scallops 2 previously discussed in connectionwith Figs. 1 to 6, but being assembled transversely of the laminae theyline up to form grooves. As herein used therefore the word scallopsis tobe understood toinclude either the edges of the strips of Figs. 1-6 orthe edges of the strips Figs. 7-9.

Such a rack, as viewed in the plan of Fig. '7 may be variouslyfabricated, but my concept makes possible economies in production bywhich my racks are made available at low cost and on a high standard ofaccuracy and uniformity which is staggering of the transverse grooveshowing. In 1 practice, I assemble the strips 10 on edge and ininterfacial contact at their sides.

In factory production the strips may be fed as longer stock or inpredetermined length and clamped as a laminated block and bored ordrilled with clean cut auger holes. These may all be bored at onceaccording to my method, for I space my holes in such relation to theends of the strip that upon reversal of the alternate laminae I obtainjust the desired ofiset of axis. The

bored laminated block, preferably While still in clamped assembly issevered by a thin saw kerf through the plane of centers CD, common tothe drillings (Fig. 8). For example, on the basis of Fig. 8, the stripsbored may be severed alternately turned end for end so that the endgrooves formed by the bores on the line of axes C'--D are alternatelyslightly shifted. The laminae may then be glued, bradded and permanentlyclamped or framed as at 33 as in my rack first described. Q

While racks according to my concept are intended primarily for rapidcomputation as in inventories, they are otherwise useful in handling andstorage of specie. Constructions and uses will vary with local problemsand be coordinated by accountant engineering to meet the ultimate resultdesired.

What I therefore claim and desireto secure by Letters Patent is:

1. In a coin rack of the class described, a laminated block having aseries of pockets in its surface, and comprising a plurality ofrelatively narrow strips disposed in lateral interfacial contact aslaminae of said block, some of said strips being of thickness equal tothat of a predetermined number of coins of full individual thicknessincluding strips having on one edge semi-circular scallops of thediameter of the coins to be held therein, said strips being disposed assaid laminae in relatively staggered relation with their scalloped edgesup and forming said surface pockets for-the coins being racked.

2. In a coin rack of the class described, a plurality of relativelynarrow strips of thickness equal to that of a predetermined number ofcoins of full thickness and having on their edges semicircular scallopsof the diameter of the coins to be held therein, said strips beingdisposed in lateral interfacial contact, the scallops of one strip beingslightly staggered with relation to those of the strip next adjacent andforming therewith,

pairs of rows of pockets extending in a series along the strip edges.

3. A coin rack according to claim 2 in which the staggering of thescallops at the edges of adjacent strips is less than their widthwhereby the pocket ends are only partlyclosed by the overlap of thecurvature of the scallop walls.

4. In a coin rack of the class described, a plurality of relativelynarrow strips of thickness adjacent strips having pockets of differentdenominations by strips having plain edges disposed as barriers acrossthe side openings of the adjacent pockets,
